Stand by for space weather: three coronal mass ejections were released by the sun in the past few days and are aimed directly at the earth. The first hit tonight, without doing much damage.
Though it is important to prepare for these solar storms, don’t expect them to do much harm. Power companies use the warnings to protect their grids. What you can expect is an increased chance of seeing the aurora at lower latitudes.
A truck 400 feet long with 192 wheels crosses California to Utah.
Boeing has now officially chosen the Atlas 5 rocket to launch is manned capsule.
Two Russians have completed a spacewalk today at ISS. They not only prepared the station for future Russian upgrades, they released an amateur radio microsat.
Cost issues might force Europe to downsize its 2016 Mars mission.
The Atlas 5 is the rocket that Boeing, Blue Origin, and Sierra Nevada plan to use to get astronauts into orbit.
A lack of U.S. government interest in a privately designed satellite refueling technology has caused the company to pull back its plans.
MDA had signed a contract with the communications satellite company Intelsat to refuel some of its orbiting satellites, but needed additional customers to make a go of it. It had hoped the U.S. Defense Department would show interest, but they have not.
This is exactly where the government should be investing its capital, and that it is not tells us a lot about the real lack of sincerity behind the Obama administration’s claims that it wants to encourage private space. I also suspect that the turf war with satellite companies and defense contractors helped discourage Defense Department interest.
A look at the more than 450 tourists who have paid a deposit to Virgin Galactic to fly in space.

The drought in Texas has uncovered in a lake a possible piece from the destroyed shuttle Columbia. More here.
Chris Bergin at NASAspaceflight.com today wrote a report on the four companies NASA is subsidizing to build manned capsules. The status of each company tells us something of whether they can eventually provide the United States with a replacement for the shuttle, and do it soon. Let’s take a look at each.

The Dawn science team today released what they are calling “the first full-frame image” of Vesta. The image is shown below the fold.
The picture was taken from 3,200 miles, and shows a pockmarked irregularly shaped world. While many features that resemble the Moon (the craters, the rays radiating out from those craters), that Vesta itself is not spherical makes it very much unlike the Moon. It is probably going to take scientists several months at least to decipher the data they are getting and come up with some concrete conclusions about this strange dwarf planet.
